Answer is result from evolution in a similar environment
The analogous structures are the various structures in different species having the similar in function because face similar environmental pressure, but have different in their origin. These structures evolved separately. Thus, they do not share common ancestor. For example are wings of birds and wings of insects, fins of fish and flippers of whales. Analogous structure supports convergent evolution.
Any herbivores would have thrived if left alive. same with the smaller predators like foxes or owls. populations shoot up. increase in inbreeding if the islands are isolated and eventually disease catches up with them
The reasoning behind this could be a part of personal beliefs and or the opinion of that person viewing it as animal abuse. this point of view is based on the individual.
